GM Body Control Module BCM 15299986 Programmed

Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or even a car that won’t start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and seemingly unrelated problems. This replacement BCM, part number 15299986, is the definitive solution to restore your vehicle’s proper function.

We take the guesswork and hassle out of the repair. Unlike a standard replacement that requires a trip to the dealership for expensive programming, this module arrives at your door pre-programmed with the latest GM software updates, specifically matched to your vehicle’s VIN. This ensures a seamless integration and gets you back on the road faster.

Common Symptoms of a Failing BCM

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, door locks, or mirrors working intermittently or not at all.
• ✔ The security system or keyless entry failing.
• ✔ The vehicle failing to start, even with a good battery and starter.
• ✔ Warning lights for various systems (ABS, Airbag, Traction Control) appearing on the dash.
• ✔ Radio or infotainment system malfunctions.
• ✔ Wipers activating on their own or not working when needed.

Your Plug-and-Play GM Body Control Module Solution

This unit is a direct replacement for a wide range of GM vehicles, including popular models like the Chevy Impala, GMC Acadia, Cadillac DTS, and Chevy Express vans. By providing your VIN during checkout, you ensure that the module you receive is a perfect electronic match for your vehicle’s specific options and configuration. This eliminates the need for advanced scan tools for initial setup, saving you time and money.

Installation and Required Procedures

While the physical installation is often straightforward (typically involving unplugging the old module and plugging in the new one), some vehicles may require post-installation relearn procedures. For example, if your airbag light is illuminated after the swap, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary to ensure brake lights and traction control function correctly. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
